For some reason r3 gets clobbered and we still end up with a broken stack. Posted v2 that simply migrates SP_svc to SP_hyp.

I can run helloworld.efi on my board with this diff. > Which board are you on? Technexion PICO-PI-IMX7; it's a board with an i.MX7D SoC. I have a Banana Pi as well, so I'll give that one a go tomorrow. ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
